The Morco Primo EUP11 with piezo ignition. The Morco G11E flue fits the EUP11 directly.
An EUPFK fitting/Conversion kit will be required will be required to fit the water heater.
The new Morco EUP11 Litre water heater is an EUP compliant direct replacement for the G11E and MP11.
The flue diameter is the same at 110mm, so if you are replacing a G11E you can use the existing flue.
